Exploiting the full Gaia data: From Bayesian isochrone fitting to transferring spectroscopic stellar parameters to 1 billion Gaia DR3 stars Abstract I will present a new stellar-parameter catalogue obtained from Bayesian isochrone fitting for 400 million Gaia EDR3 stars (cross-matched with...
Supplementary Elements*, c'est un parcours d’œuvres à découvrir sur le campus de l'Esplanade, du lundi 25 avril au dimanche 22 mai 2022. Supplementary Elements* propose un nouvel éclairage quant aux liens unissant avancées scientifiques d’aujourd’hui et expressions artistiques...
A new picture for the Large Magellanic Cloud-Milky Way interaction Abstract Over the past decade, our understanding of the Large Magellanic Cloud (LMC) and its relationship to the Milky Way (MW) has undergone a paradigm shift. The LMC now appears to be on the order of 20% of the MW mass. At...
Early Career Researchers the Harbingers of Change: attitudes, behaviours and strategies regarding the changing world of scholarly communication Abstract This presentation is related to an international study informed by a 5-year-long qualitative longitudinal project, which sought to...
Galactic Archaeology with the oldest stars in the Milky Way Abstract The oldest, most metal-poor stars we find in the Milky Way today were born in pristine environments in the early Universe. They contain unique clues about the First Stars and the early formation and evolution of our Galaxy....
Probing the first galaxies and cosmic reionization with the James Webb Space Telescope Abstract The role of dwarf galaxies in the star formation history of the universe has long been overlooked, primarily because of observational challenges and the predominance of bright,...
Le projet ESCAPE organise sa deuxième école internationale sur l'Observatoire Virtuel sous la forme d'une réunion hybride à l'Observatoire Astronomique de Strasbourg, et en ligne dans Zoom. L'école aura lieu du 22 au 24 février 2022 et le 04 mars 2022. L'Observatoire Virtuel (OV) ouvre...
On the causal origin of properties of dark matter halos and galaxies Abstract Large-cosmological simulations, such as Illustris-TNG or Horizon-AGN, allows to draw relations between the formation history of galaxies and their host haloes (number of mergers, formation time) and their...
Strong lensing: Illuminating galaxies clusters and the structures behind them Abstract The strong gravitational lensing effect is a powerful technic to study both the deflector of light and the magnified sources behind it. In this talk, I will first review mass modelling approaches of galaxy...
Quasar feedback and the origin of extended Lyα glow in z > 6 quasars AbstractThe detection of quasars out to z ≈ 7.5 shows that supermassive black holes with masses of ≈109M☉ have already assembled by the time the Universe was only ≈ 680 Myr old. These observationsstrenuously...
